57-60-00 AILERONS
The construction of the ailerons is the same as the wing, but they have only one spar. The
spar is a honeycomb sandwich type with carbon fiber laminate. It is attached at five points.
All composite parts have different protective layers: a polyester layer, an acrylic filler and an
acrylic paint to prevent damage to the structure because of moisture and UV radiation.
To remove the ailerons:
1 Remove the wing, refer to chapter 57-10-00.
2 Remove the hinge pin (5mm Allen key).
3 Remove the aileron.
4 Assemble the ailerons in the opposite sequence. Torque the hinge pin to 15 Nm (11
lbs/ft).
5 Do these checks:
The ailerons must move freely from stop to stop.
Deflection, tolerance and permitted play must agree with Table 27-1 .
The ailerons have spades to decrease the control forces. For information on the spades,
refer to chapter 27-10-01.
To put shim washers to the ailerons, do these steps:
Measure the aileron play:
1
Move the aileron to the inboard side.
2 Measure the inboard and outboard clearance between the hinge horn of the aileron
and the aileron at each hinge.
3 Select the necessary shim washers (DIN988 d=6mm, 1mm or 0.5mm thick) for each
of the ten (10) positions for each aileron. We recommend that you use a minimum
of washers at each position.
Install the shim washers:
4
Remove the wing, refer to chapter 57-10-00.
5 Remove the ailerons from the wing.
6 Put the aileron hinge pin through the hinge horns of the aileron. Put the selected
washers through the aileron hinge pin between the hinge horns of the aileron.
7 Bond the washers to the horns with instant glue.
